Well, in theory....

Whack a tree onto a very big rocket and launch it into space, use a few 
gravity assists to pick up speed around some planets and stars... as it 
gets faster the light returning from it will have a longer wavelength ... 
but you may need a good telephoto lens.

This could be useful for those pesky species of conifers that resist a nice 
IR effect

... rough day at the office  ;-)
